Published Beetle that pushes dung with the help of 100 billion stars unlocks the key to better navigation systems in drones and satellites



An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.
Published The power of face time: Insights from zebra finch courtship



A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.
Published 'DNA scavengers' can stop some antibiotic resistance from spreading



For nearly a century, scientists have waged war on antibiotic-resistant microbes. Researchers say they've found a new way to prevent it -- by unleashing 'DNA scavengers' in wastewater treatment plants.
Published Engineered Bacteria make thermally stable plastics similar to polystyrene and PET



Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable. Because these molecules are usually toxic to microorganisms, the researchers had to construct a novel metabolic pathway that would enable the E. coli bacteria to both produce and tolerate the accumulation of the polymer and the building blocks it is composed of. The resulting polymer is biodegradable and has physical properties that could lend it to biomedical applications such as drug delivery, though more research is needed.
Published Benefits and downside of fasting



Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.
Published Self-repairing mitochondria use novel recycling system



A newly identified identified cellular mechanism allows mitochondria to recycle localized damage and maintain healthy function.
Published Surprising mechanism for removing dead cells identified



A tandem signaling process turns ordinary cells into an efficient cleanup crew.
Published Compound in rosemary extract can reduce cocaine sensitivity



A team of researchers has discovered that an antioxidant found in rosemary extract can reduce volitional intakes of cocaine by moderating the brain's reward response, offering a new therapeutic target for treating addiction.
Published Researchers teaching artificial intelligence about frustration in protein folding



Scientists have found a new way to predict how proteins change their shape when they function, which is important for understanding how they work in living systems. While recent artificial intelligence (AI) technology has made it possible to predict what proteins look like in their resting state, figuring out how they move is still challenging because there is not enough direct data from experiments on protein motions to train the neural networks.
Published Mother's gut microbiome during pregnancy shapes baby's brain development



A study in mice has found that the bacteria Bifidobacterium breve in the mother's gut during pregnancy supports healthy brain development in the fetus.
Published How early-life antibiotics turn immunity into allergy



Researchers have shown how and why the depletion of microbes in a newborn's gut by antibiotics can lead to lifelong respiratory allergies. The research team identified a specific cascade of events that lead to allergies and asthma, opening many new avenues for exploring potential preventions and treatments.
Published 'Masters of shape-shifting': How darkling beetles conquered the world



Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published New worm study paves way for better RNA-based drugs to treat human disease



Researchers have discovered RNA mechanisms that may lead to more effective, durable and targeted treatments for conditions like high cholesterol, liver diseases and cancers.
Published Deadly sea snail toxin could be key to making better medicines



Scientists are finding clues for how to treat diabetes and hormone disorders in an unexpected place: a toxin from one of the most venomous animals on the planet.
Published Scientists discover new code governing gene activity



A newly discovered code within DNA -- coined 'spatial grammar' -- holds a key to understanding how gene activity is encoded in the human genome. This breakthrough finding revealed a long-postulated hidden spatial grammar embedded in DNA. The research could reshape scientists' understanding of gene regulation and how genetic variations may influence gene expression in development or disease.
Published Researchers uncover the secrets of 'plant puberty'



Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Gut microbial pathway identified as target for improved heart disease treatment



Researchers have made a significant discovery about how the gut microbiome interacts with cells to cause cardiovascular disease. The study found phenylacetylglutamine (PAG), produced by gut bacteria as a waste product, then absorbed and formed in the liver, interacts with previously undiscovered locations on beta-2 adrenergic receptors on heart cells once it enters the circulation.
Published Researchers develop an instant version of trendy, golden turmeric milk



If you've visited a trendy cafe in the past few years, you might have noticed 'golden' turmeric milk on the menu. This fancy drink is caffeine-free, coffee-free and can even be vegan. And now, researchers have developed an efficient method to make a powdered, plant-based, instant version that maintains the beneficial properties of the ingredients while also extending its shelf life.
Published Key biofuel-producing microalga believed to be a single species is actually three



When a global pandemic forced previous a graduate student out of the lab and onto the computer, he found a world of difference hidden in the long-studied species of Botryoccocus braunii -- and discovered that it isn't one species at all, but three.
Published How 'winner and loser effects' impact social rank in animals -- and humans



A new article provides a narrative review of the relevant similarities and distinctions between nonhumans and humans to assess the causes and consequences of winner and loser effects in humans.
